This is a custom CNC collet chuck, not an off-the-shelf item. You send the print. We make the collet.
| Parameter | Value |
|---|---|
| Type | 32 Type (DIN 6343 compatible) |
| Bar stock shape | Hexagonal, sizes 4 mm to 32 mm across flats |
| Bore tolerance | ±0.005 mm |
| Concentricity | ≤0.008 mm TIR |
| Hardness | 58–62 HRC (case-hardened) |
| Surface finish | Ra 0.4 µm on bore, Ra 0.8 µm on outer diameter |
| Material options | 20CrMnTi, 40Cr, 9SiCr, or per your spec |
| Process | CNC turning, internal grinding, wire-cut slotting |
| Heat treatment | Carburizing + quenching + tempering |
| Batch size | 1 to 10,000 pieces |
| Inspection | 100% dimensional check, report per batch |
We use CNC lathes and internal grinders for the bore. The hex profile is wire-cut to maintain sharp corners. Each collet is individually tested with a hex gauge pin before packing.
1. Batch-traceable quality. Every batch gets a unique heat number. Material certs are stored for 5 years. If you have a problem, we trace it back to the exact melt and machining shift. No ambiguity.
2. Inspection report per batch. You get a full dimensional report with CMM data, hardness readings, and surface roughness values. This is not a generic certificate. It matches your drawing callouts line by line.
3. One factory for CNC + stamping + spring + heatsink. You are not just buying a collet. You are buying a vendor who can also make the spring that holds it, the stamping that mounts it, and the heatsink that cools the spindle. Fewer suppliers, fewer logistics headaches, one quality standard.
The 32 Type collet with hex bar stock is used in automatic lathes and Swiss-type machines. Typical applications:
If you machine hex bar stock on a CNC auto lathe, this collet is the interface between your spindle and your material.

Q: What is your MOQ? A: No MOQ. We make one piece for prototype validation, then scale to production. Many buyers start with 5–10 pieces to test fit and run speeds.
Q: How do you control tolerance and quality? A: We use CNC grinding for the bore and wire-cut EDM for the hex slot. Every collet is measured with a CMM and a hex gauge pin. The inspection report is included with your shipment.
Q: What is your lead time? A: Standard sizes: 7–10 working days. Custom materials or special heat treatment: 12–15 working days. We ship via DHL or FedEx, door to door.
Q: Can you provide material certificates? A: Yes. We supply mill certs for the raw bar stock and our own heat treatment report. Both are traceable to your batch.
